摘要：
The conduction of mobile alkali ions in single-crystal one-dimensional (1D) superionic conductor (K-Cs)-priderites, KxCsyMg(x+y)/2Ti8-(x+y)/2O16, was studied by means of ac complex electrical conductivity measurement from 100 Hz to 9.8 GHz. The ion conduction behavior can be described by the moving-box model [1]. The motion of K+ ions was different from that in K-priderite, though the average distance L between the two succeeding Cs+ ions was large. This result shows that the correlation length lambda(c) for K+ ions is longer than L.
